“…Different countries may have experienced distinct patterns of background mortality, especially in connection to their aging populations, which account for the vast majority of deaths from a variety of underlying conditions. In Asian locations such as Taiwan, Baby Boomers born between 1946 and 1964 have accelerated the aging population aged 65 years or older, especially since 2015 [10], which may result in an increase in background mortality. Moreover, an older population would have a substantial impact on medical capacity if a large-scale outbreak of COVID-19, particularly Omicron VOC (Variant of Concern), occurred in a community.…”

Background: Asia's elderly Baby Boomer demographic (born between 1946 and 1964) faced a huge problem during the COVID-19 pandemic due to increased all-cause mortality. We aimed to provide a unique Taiwan situation regarding the impact of Baby Boomers on excess mortalities from all causes relative to non-Baby Boomers throughout distinct times of SARS-CoV-2 mutations during the COVID-19 pandemic. Methods: The Poisson time series design with Bayesian directed acyclic graphic approach was proposed to build the background mortality prior to the COVID-19 pandemic in 2015-2019. It was then used for predicting the expected all-cause deaths compared to the reported figures during the COVID-19 pandemic period based on Taiwan residents, a naïve Omicron infection cohort. Results: Baby Boomers experienced a 2% (95% CI: 1%-3%) negative excess in 2020 (Wuhan/D614G) and a 4% (95% CI: 2%-5%) excess in 2021 (Alpha/Delta), relative to non-Baby Boomers, due to a rising mortality trend for Baby Boomers, but remained constant for non-Baby Boomers. Baby Boomer and non-Baby Boomer mortality rates soared to 9% (95% CI: 7%-10%) and 10% (95% CI: 9%-11%), respectively. Surprisingly, Baby Boomers aged 58-76 experienced the same 9% excess mortality as non-Baby Boomers aged 77 and beyond. Non-COVID-19 deaths were more prevalent among Baby Boomers than non-Baby Boomers (33% vs. 29%). Conclusion: Baby Boomers were more likely to die from COVID-19 and had more non-COVID-19 deaths than older non-Baby Boomers. For this vulnerable population, adequate access to medical care and medical capacity require more consideration.

Background Asia’s elderly Baby Boomer demographic (born between 1946 and 1964) faced a huge problem during the COVID-19 pandemic due to increased all-cause mortality. We aimed to provide a unique Taiwan situation regarding the impact of Baby Boomers on excess mortalities from all causes relative to non-Baby Boomers throughout distinct times of SARS-CoV-2 mutations during the COVID-19 pandemic. Methods We used the Poisson time series design with a Bayesian directed acyclic graphic approach to build the background mortality prior to the COVID-19 pandemic between 2015 and 2019. It was then used for predicting the expected all-cause deaths compared to the reported figures during the COVID-19 pandemic period based on Taiwan residents, an Omicron-naïve cohort. Results Baby Boomers experienced a 2% negative excess mortality in 2020 (Wuhan/D614G) and a 4% excess mortality in 2021 (Alpha/Delta) with a rising background mortality trend whereas non-Baby Boomers showed the corresponding figures of 4% negative excess and 1% excess with a stable trend. Baby Boomer and non-Baby Boomer excess mortality soared to 9% (95% CI: 7-10%) and 10% (95% CI: 9-11%), respectively, during the epidemic Omicron period from January to June 2022. Surprisingly, Baby Boomers aged 58–76 experienced the same 9% excess mortality as non-Baby Boomers aged 77 and beyond. Non-COVID-19 deaths were more prevalent among Baby Boomers than non-Baby Boomers (33% vs. 29%). Conclusion Baby Boomers were more likely to die from COVID-19 in early pandemic and had more non-COVID-19 deaths in late pandemic than older non-Baby Boomers demonstrated in Taiwan Omicron-naïve cohort. For this vulnerable population, adequate access to medical care and medical capacity require more consideration.
